You can remove the uibinder-bridge when using GWT 2.5.0. The features that the bridge added are now part of GWT 2.5.0 directly.

When I droped the uibinder-bridge-2.4.0.jar from the gxt lib, another error occured:

Loading inherited module 'com.sencha.gwt.uibinder.UiBinder'
[ERROR] Unable to find 'com/sencha/gwt/uibinder/UiBinder.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?
